separation, no color. |

White, dim, with a N/S
orientation. To the NW in the field of view are 2 other stars making a
triangle with the pair at the vertex. The other 2 I later ID'ed as
Tycho 122987 and 122986.

The AB components of this
system are wide and easy to split at 71x. Both
components are white. I was able to split BC at this power also: the
13th-magnitude companion to B was seen with direct vision but easier
with
averted vision. It was white also. |

Easy and
wide pair. Best in the 12.5mm at 64x. Could not detect the C component - maybe because of the haze? Soem color on the A, a little warm white. |
